Reed Switch
A Reed Switch is a basic but important safety device found in many home appliances and equipment. Think of it like a small sensor that can detect when a door is opened or closed. It's made of two metal pieces that either connect or disconnect when a magnet comes near them. You'll often find these in washing machines (to stop the machine if the door opens), refrigerators (to turn the light on and off), or security systems. When maintenance workers mention Reed Switches in their experience, it means they know how to work with these safety components and can diagnose, replace, or repair them.
